Just hours after his latest date with Kendall Jenner, One Direction's Harry Styles was spotted out shopping in Manhattan with aspiring model Kara Rose Marshall, the Huffington Post reports. Is the One Direction heartthrob also a heartbreaker?

On Tuesday, Dec. 10, Styles took Marshall out for some shopping and lunch not long after leaving Therapy, a gay bar in NYC, with Kendall Jenner. The two reportedly "didn't make a huge deal about" the outing, as they were joined by a group of friends and apparently didn't partake in any dancing. However, Now magazine sources claim that big sister Kim Kardashian and her fiancé Kanye West have been warning Jenner to stay away from Styles, as West feels that "rock stars can be dogs," and apparently Kardashian agrees.

"Harry and Kendall have been circling each other since being introduced a few months ago and are finally taking that next step," the Now insider said. "But Kim knows all about being played and fears Kendall will get hurt by the king of heartbreakers."

Insiders also warn that Styles risks an invite to Kardashian's big wedding, which may take place in France at the Palace of Versailles, if Kanye West has anything to say about it. Along with his outings with Jenner, Styles was seen leaving the Malibu home of her father, Bruce Jenner, at 9:00 a.m. last month, just hours before he took the 18-year-old reality star out for a lunch date.

Of course, Styles may not be dating Jenner or Marshall and might simply be close friends with a lot of famous women. E! News sources, however, claim that Marshall is Style's latest love interest. The two share several mutual friends, and were both spotted with Style's hairdresser, Lou Teasdale, at the Apple store while hanging out in NYC.
